1815673 - Drag scrolling a menupopup also selects text in parent window

Status: RESOLVED DUPLICATE of bug 1815370

(Firefox :: Menus, defect)

Description

[Hartmut Welpmann [:welpy-cw]]

Attachment: drag scrolling menupopup

Open about:preferences, click on font selection menu and keep mouse button pressed down. When the mouse pointer leaves the popup menu while drag selecting, text outside of the menu gets selected too (see video). This didn't happen before this regression was introduced:

I already tried to simply replace the deprecated setCaptureAlways() and releaseCapture() calls in toolkit/content/widgets/menupopup.js with setPointerCapture() etc., but then drag scrolling wouldn't work at all.

Sorry, I didn't see this has already been reported just yesterday.

(No worries, best to have it on file twice than zero times :))
